and i asked him about the environment. he said we don't have an environment. we can't afford one. and that was very much the story of the 1990s. the signature of the russian hydrocarbon industry is absolutely conventional up to this point, and their investment level in investment in renewables and unconventionals is at this point effectively minimal with one big exception, and that's nuclear power, if you consider that to be a virtuous renewable. as for solar, well, the agency that is in charge is, in fact, subordinated to the nuclear power agency which tells you something. and so on. so this is a story that has not yet begun. it's something that the russians are going to have to become more conscious of if only for one very direct reason. the entire northern third of russia is perma frost, and the perm frost is melting. and the consequences of a massive melting of perm a frost are particularly serious in russia. the economic disruption alone, never mind the environmental consequences. so we're talking about big downsides to this guilty love story. >> one last question? >> thank y
